Sometimes we want to collect crystals and metals and make things with them. Other times, we just want to dress our sims. Sometimes we want to have both earrings (https://www.curseforge.com/sims4/create-a-sim/unlocked-crystal-earrings) AND the matching necklaces.
13 necklaces, always available in CAS, for masculine and feminine clothing preferences, but restricted to feminine frame (the masculine frame version exists, but is an entirely separate object. I might get to that eventually).
Except for two (Basic and Botched, which have one swatch each), they have the 28 original swatches. All metal is the same grey.
Disabled for random. Most enabled only for Everyday, Formal, Party, Hot Weather and Cold Weather. Botched is Everyday, Hot and Cold only. Otherwise the tags are the same as the originals.
They REQUIRE the Crystal Creations Stuff Pack. (Or red and white sims with question marks will occur.)
If you craft a necklace in game and have a sim wear them, the necklace will be available in CAS twice. That is the way things work, nothing I can do about that.
